PAPER-Box MACHINE.

SPECIFICATION forming part of Letters Patent No. 586,803, dated July 20, 1897. Application filed February 21, 1896. Serial No. 580,220. (No model.)

T0 all whont it ma]] conccrn:

Be it known that I, CHARLES F. TAYLOR, a citizen of the United States, and a resident of Holyoke, in the county of Hampden and State of Massachusetts,have invented certain new and useful Ilnprovements in Paper-Box Machines, of which the following' is a specification.

This invention relates to machines for making paper or cardboard boXes from blanks having flaps and stay-sections substantially such as illustrated in the accompanying drawings.

The object of this invention is to produce an improved machine for making boxes of the description nained which is very simple and inexpensive in construction and which may be easily adjusted and arranged for adapting it to the production of boxes which are variable as to length or breadth, or both.

The invention consists in certain novel constructions, parts, and combinations thereof, all substantially as will hereinafter fully appear, and be set forth in the claiins.

The present improvements are fully and clearly illustrated in the accom panyin g drawings, in which- Figure 1 is a plan view of the Vilnproved machine. Fig. 2 is a Vertical section thereof, taken on the line 2 2, Fig. 1. Fig. 3 is a perspective view illustrating the novel folding or fiap-turning devices. Fig. 4 is a Vertical sectional view through the plunger and through the side-lap turners, the plunger being understood as being in a position relative to the said folders which it assumes in its downward movernent. Fig. 5 is a sectional view showing the plunger and the devices that coperate with the plunger which set the end flaps. Fig. 6 is a view illustrating an appliance niounted on the side-flap folder for checking any tendency of the completed box to return upwardly with the rising retreating plunger. Fig. 7 is a side view of the adjustable journal-box for one end of the end-setting device. Fig. S is a sectional view on line S 8, Fig. 2. Fig. E) is a plan view of the blank from which the box is made.

Similar characters of reference indicate corresponding parts in all of the views.

The novelties in the present machine reside in the folding or fiap-turning mechanisms and adjuncts thereof and also in certain improved means whereby the bars of the blank-conveyer are adjusi'able transversely of their length, so that they may advantageously engage and carry blanks of varying lengths.

Some of the mechanisms and movements of the machine on which the present improvements are applied are analogous to those which have been heretofore commonly and extensively used in envelop-machines, and in this connection it will be notcd that the blanks (indicated at a in the drawings) are provided in a pile and picked up by pickerand-gummer mechanism in the ordinary way.

The gumm ers (indicated at b by dotted lines) are preferably adjustable, so that the gumming members 62 thereof may have approached or widened relations to correspond to the size and shape of the blanks. Such picker-gummers are common in the art to which this invention pertains.

The blanks from which the paper boXes are made embody, in addition to the central portion 12, which forms the bottom, (or the top, if for a boX-cover,) the side flaps 13 13, the end flaps 14 14., and the stay-Sections 15 15. The flaps 13 13 14 14 are folded up right angular to the bottom, and the stay-Sections, which are carried by the side fiaps, are folded inwardly at right angles and are stuck to the end flaps. (See Figs. 3 and 9.)

The dotted lines in Fig. 9 represent the lines in which the blank is folded. The blanks are usually scored on these lines previous to being placed in the machine to be automatically fed to the box-forming mechanism.

The conveyer A consists of the two conveyer-bars d (Z, having hooked ends (22, as nsual, together with the cross-rod C13, to which the bars are connected, and the cam-actuated lever C14 for imparting the bodily movement to the said bar and the slide movements to the conveyer-bars.

The conVeyer-bars may have widened or approached positions in setting the machine for work by reason of the binding-nuts (Z5 d, which engage the rod (13 at each side of the said bars. Said bars are supported to slide longitudinally in suitable ways therefor, which are provided in the uprights B B.

IOO

` flap turners.

These supporting-uprights are mounted at the lateral edges of the opening through the table C and are transversely adj ustable in the ways f. The said uprights have the shoulder q just above their bas'e portions, which fit in the ways and are confined with said shoulders firmly against the marginal portions of the said ways by the clarnp plate and nut Q2 Q3.

It will be here stated that in the above connection the term longitudinally of the machine is employed to designate the direction of movement of the conveyer, while laterally and (*ti'ansvei'sely are comparatively used to designate direction which is right angular to said feed movement of the conveyer. D represents the former-plunger, which is of rectangular plan and which is reciprocated vertically by a cam movement, as usual in envelop-machines and in this class of boxmachines. The former-plunger is shown as carried at the lower end of the plunger-shaft D2, which depends below the cross-head D3. The cross-head is supported by the Vertical bars D4, against which the duplicated cam D5 operates to lift, the descent being by gravity when the weight of the parts is sufficient, or the descent may be by positively-operating mechanism, not necessary to describe, as the means for acquiring a suitable reciprocatory movement on the plunger con stitutes no part of the present invention.

The plungerD is detachably confined in any suitable way on the lower end of the plungershaft, whereby one plunger of a given size may be interchanged for one of a different size.

In front and behind the path of the foldingplunger and ranging transversely of the machine in parallelism are the rock-shafts F F,

on which are the side-fiap turners g g and the stay-section turners h h, the latter appearing as right-angular lips on the ends of the side- The said rock-shaf ts are mounted in their horizontal positions in the brackets or standards t' therefor, which rise above the table C, and the springsjj, applied on the rock-shafts F, maintain such shafts and the said folders g thereon normally in the horizontal positions indicated in Figs. 1 and 2. Said upstanding stay-section turners h are arranged longitudinally of the folders g, being at the lateral edges of said folders and at or near the ends of the same farthest from the former-plunger. The inner ends of the turners g project. within or across the path of the plunger, so that when the latter descends by contacting with said inner ends the sidefiap turners are tipped up toward and finally are brought against the plunger, as seen in Figs. 3 and 4.

The brackets t' 72, in which the rock-shafts F F are journaled, are adjustable longitudinally of the machine, the slotted bases i and confining-bolts being practical provisions to this end.

The blank, which is brought by the conveyer over the flap-turners g g, is subject to the coperative action of said turners and the plunger, the stay-Sections extending longitudinally beyond the stay-section turners h h, and therefore as the plunger descends the stay-Sections are caused to assume angular relations to the general plane of the blank and toward the ends of the plunger, followed by the upturning of lthe side flaps as caused by the rocking of the side-fiap turners g g.

The descending plunger forcing the blank downwardlycauses the end iaps to be turned upwardly toward the end of the plunger by reason of the impingement of said fiaps against the conveyer-bars, below the plane of which bars the blank is borne, and the side fiaps and stay-sections having been brought into contact with the sides and ends of the plunger about the time the blank is brought to the opening. in the table the partiallyturned end Sections may be now set against the stay-Sections by the operation of the endsetting mechanism, which will be now described.

G G represent rock-shafts which are m ounted below the aforesaid rock-shafts F, on which the side-flap turners are mounted and at right angles thereto. These rock-shafts have formed or affixed thereon the eccentrics or cams, having peripheries as long as the width of the widest boxes to be made in the machine.

Each rock-shaft G has on its end a pinion m. The plunger D has combined to move in unison therewith the dependin g rack-bars J J, which when the plunger is elevated are out of mesh with said pinions G, but which as the plunger approaches the limit of its downward movement are brought into mesh with the said pinions, causing such a rocking movement of the rock-shafts as to bring the more prominent portions of the end setters H H to pressure against the end flaps, (near the ends of which the gum has been applied,) forcing and setting them hard against the stay-Sections 15 15, the latter being in contact against the ends of the folder-plunger. The said rockshafts G G are mounted in the journal-blocks k, each of which is movable in the aperture 7t2 therefor in the bracket M and against the cushion or spring 7x23, (see Fig. 7,) the said cushion being under a variable compression as effected by the adjusting-screw R4. Each of the said brackets M is, as permitted by the confining bolt and slot seen at 705, adjustable transversely of the machine, so that the endsetting mechanism may be farther separated or approached to accord with the variability in the lengths of the boxes to be made in the machine.

It will be perceived on reference to Figs. 1, 2, and 3 of the drawings that the rack-bars J J are adjustable, in order that their coperative action with the end-setting devices may always be maintained.

The plunger-shaft D2 is seen to have the rearwardly-proj ected bracket n,havin g thereon the horizontal transversely-ranging mem- IOO IIO

ber 012, which has the grooved ways ng and also the slots ni. The rack-bars are secured in clips or clamp-blocks ns, which are movable in said ways, and said clamp-blocks are retained in their set positions by the con finingbolts ns.

The side-fiap and stay-section turners g 72, are adjustable along the length of the rockshaft which carries them by the provision of the perforated hubs g2 of the turners g, whereby the latter may be slid along the rock-shaft, and the set-screws Q3.

As seen, in addition to the turners g g, which operate at the Corners of the box7 there is 011 the rock-shaft another somewhat similar turner, (design ated by g',) which advantageously assists in the turning np and forcing of the side fiap againststhe plunger, preventing warpin g or bulging.

One or more of the side-fiap turners g g or g' has projecting belowits lower edge a springfinger (/4, the action of which is indicated in Figs. I and G. The plunger finally forcing the blank below the turners g gas low, for instance, as seen in Fig. -snaps past the angular extremity of the said spring-finger Q4, which gives way thercto, assuming a position above the upper edge of the box and serving to strip the box from the plunger as the latter returns upwardly.

It will be observcd in this machine that the plunger and the rack-bars niovable in unison therewith effect in proper time and without any special cam -actuated mechanisms the roching inovements of the side-flap and staysection turners and the rolling movements of the end-setting devices.

lIaving thus describcd my invention, what I claim, and desire to secure by Letters Patent, is-

l. In a paper-box machine the combination with a reciprocatory former-plunger, of fiapturners mounted to have rocking moveinents and having portions thercof extending across the path of the plunger, said fiap-turners having the spring-iingers projecting beyond their inner edges for preventing the finished box from beingl carried with the plunger on the return of the latter, substantially as described.

2. In a paper-box machine the combination with the reciprocatory former-plunger of the rolls having ecccntric peripheries, mounted in parallelism at opposite sides of and adjacent the path of the plunger7 having a length greater than that of the adjacent surface of the plunger, means for causing the rolling movement of said rolls in conjunction with the descent of the plunger, and opposing paired flap-turning mechanisin bodily adjustable toward and away from the plunger in lines at right angles to the length of said eccentric rolls, substantially as described.

3. In a paper-box machine the combination with an interchangeable reciprocatory former-plunger7 of a flap-setting mechanism consisting of rolls having cam-like peripheries and yielding journal-supports in which said rolls are mounted which are adj ustable transversely of the lengths of the rolls, and all arranged for operation to set the fiap of a paper box against the former, substantially as described.

4. In a paper-box machine the combination with an interchangeable plunger, the endsetting cam-rolls having the gears thereon, and adjustable supports in which said ro11s are journaled of the racks inounted to move in unison with the plunger and adjustable toward and from each other, substantially as and for the purpose set forth.

5. In a paper-box machine the combination with the plunger-shaft and intcrchangeable plunger, the adj ustable end-setting cam-rolls having the gears thereon, and adj nstable supports in which said rolls are journaled, of the bracket n having the member 712 which has the slideway ng and the slots 'af the clips or blocks '17,5 adj ustably fitted in said ways, the confining-bolts n, and the rack-bars, .I J supported by said blocks 715, substantially as described.

6. In a paper-box machine in combination the table having an opening therethrough, a former-plunger, rocking side flap turners having the stay section turners mounted tl1ereon,\\ithportions of said flap-turners projecting across the path of the plunger, said folders being adj ustable bodily longitudinally of the machine and individually adjustable transversely of the machine, and end-setting devices which are adjustable transversely, substantially as described.

7. In a paper-box machine the combination with the table having an opening therethrough of side flap turners, with the staysection turners thereon, mounted to have rocking movements, having portions thercof extendin g across the path of the plunger, and being individually ad jnstable transversely of the machine and the conveyer having the horzontal bars thercof adjustable transversely, substantially as described.

8. In a paper-box machine the combination with the plnnger, of the rock-shafts and longitudinally-adj ustable brackets in which said rock-shafts are journaled, the side-fiap turners g g ndividually adjustable along said shaft, having Vportions thercof projected inwardly across the path of the plunger and each having the upstanding lip or flange h which constitutes a stay-section turner, the intermediate auxiliary side-flap turner g' on each rock-shaft, and Springs applied on said shafts for normally maintaining the flapturners in horizontal positions, substantially as described.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two witnesses.
